Design and Analysis of Stepped Impedance Microstrip Fractal Low Pass Filter
Most communication system contains an RF front end which performs signal processing with RF filters. Micro strip filters are a low cost means of doing this. This paper describes the design of low cost and low insertion loss microstrip stepped impedance Fractal Low Pass Filter (LPF) by using microstrip layout which works at 0.4GHz for permittivity 4.7 value with a substrate thickness 1.6mm with pass band ripple 0.1dB. Microstrip technology is used for simplicity and ease of fabrication. The design and simulation are performed using 3D full wave electromagnetic simulator IE3D.
